Patented Oct. 13, 1936 i UNITED STATES PATENT OFFICE ANTIRATTLE DOVETAILFOR DOORS Thomas T. Logic, Bridgeport, and Arthur Claud- Mantle,Trumbull, Conn., assignors to The Bassick Company, Bridgeport, Conn., acorporation of Connecticut Application March 21,

5 Claims a wedge member engaged between them, the respective blockmembers being supported against vertical movement, whereby the rattleusually resulting from vibration and weaving of the door is preventedand the door is effectually retained against vertical movement, while atthe same time lateral movement and Wear is compensated for.

It is an object of the present invention to provide improved means forslidably retaining the lock membersin the casing, whereby accidentaldisplacement is prevented, and at the same time assembly, and removal ofthe blocks for replacement purposes, is facilitated. Another object isto provide block members which will more accurately fit in the casing,and to this end we propose to provide means for compensating "-for'slight variations in the dimensions of casing- A further object is toprovide a block member formed of sheet metal, and which will be ofhollow formation opened atthe back to provide a socket for receiving andretaining the end of the pressure spring. 7 V 1 With the above and otherobjects in view an embodiment of the invention is shown in theaccompanying drawing, and this embodiment will be hereinafter more fullydescribed with reference-thereto,--and the invention will be finallypointed out in the claims.

spending parts throughout the several figures of the drawing. Referringto the drawing the anti-rattle dovetail device, accordingto'the'exemplary illustrated embodiment of our invention, comprisesgenerally a socket member, adapted to be secured to the door framewithin a suitable recess, and a wedge member, adapted to be secured tothe edge of the door in relation to enter the socket member upon closingof the door.

The casing of the socket member comprises an outer part consisting of aface plate member l0, preferably formed of sheet metal, having aflange li at its forward edge bent at a right angle, and a lip 12 bent forwardlyfrom the flange'l l. A rearwardly converging opening I3 is provided inthe face plate and extends across the flange I l to the lip I2, theforward portion of the opening having its upper and lower edges disposedin parallel'relation. Counter sunk screw holes H are provided in theface plate near the upper and lower edges for attachment of a socketmember by screws to the door frame. l The inner or box'part of thesocket member is also formed of sheet metal, and, as shown in Figs. 4and 5, comprises a rectangular portion [5 having side wall flanges l6l 6bent from its upperandlower edges and a rear wall flange! 1 bent fromits rear edge. The flanges |6l6 have attaching ears l8l 8 bent outwardlytherefrom, and which are adapted to be secured to the face plate byspot-welding or other suitable means.

A pair of inwardly bent lugs l9-l9 are struck from the rear wall flangell for supporting the ends of the pressure springs, as will hereinaftermore fullyappear, and upon the forward edges of the sidewall flanges I6-46 there are provided projecting lugs 2020, narrower than the sideflanges and disposed intermediate their upper and lower edges, theselugs being bent rear-- wardly into spaced, and parallel relation withthe inner surfaces of the side walls.

A forwardly projecting lipt2l is provided at the forward edge of theportion I5 and is curved slightly to bring its edge into'aligmnent withthe lip l2 and to provide a guide surface for the wedge, as willhereinafter more fully appear.

A pair of opposed block members are provided in the casing, these beingof sheet metal, pressed and bent to shape. clined' slightly arcuate faceportion 22, side wall portions 2323 bent from the side edges of the faceportion in spaced and parallel relation to They each comprise an in- 5each other, a front wall portion .24 bent from the forward edge'of theface portion'in abutting relations, and a base wall portion 25 bentrearwardly from the front wall portion 24 about the rounded.

forward corner edges 26-26 of the side wall portions against the baseedges of said side wall portions. An inwardly bent lug 21 is struck fromthe base portion 25 to form'an abutment for the end of the pressurespring, presently'to be more fully referred to. An aperture 28 forreceiving the lug 20 is provided in the front wall portion 24 f Vtightly against the striker. Upon release of the its lower edge beingcut into the base portion 25;

In the assembled relation of the blocks in the socket member the lugs2020 are engaged in the apertures 28-2B of the blocks, the 'sur-faces25- 25 being in parallel relation-to each other and in slidingengagement with the side walls Iii-l6.

The blocks contact each other at their inner wide ends.
